Application November 15, 1946, Serial No. 709,952 12 Claims. (01. 1-1) This invention relates to machines for mounting or affixing tips, end pieces or ferrules to the ends of umbrella shanks, canes or the like, and is an improvement on the structure shown and described in Pat. 2,285,380, dated June 2, 1942.

One object of the invention is the provision of a ferrule pinning machine which is adapted to accommodate various sizes of ferrules by but a slight adjustment and one in which the length of wire cut ofi may be adjusted to correspond to the diameter of the ferrule.

Another object of the invention is the provision of an improved wire pin cutting and feeding mechanism for such machines.

Another object is to produce a machine of the character described in which the maximum simplicity of construction and operation is secured.

Other objects and advantages will appear as the nature of the improvements is better understood, the invention consisting substantially in the novel arrangement and co-relation of parts herein fully described, and illustrated in the accompanying drawings, wherein similar reference characters are used to denote corresponding parts throughout the several views, and then finally pointed out and specifically defined and indicated in the appended claims.

The disclosure made the basis of exemplifying the present inventive concept suggests a practical embodiment thereof, but the invention is not to be restricted to the exact details of this disclosure, and the latter, therefore, is to be understood from an illustrative, rather than a restrictive standpoint.

In carrying out the objects of the present invention it was found advantageous to provide a lower portion of the device which is adapted to be suitably secured to the bedplate of a press and an upper portion carried by the press plunger. The lower portion of the device preferably includes a socket for holding the ferrule and umbrella shank below a rotatable wire cutter, operable for cutting the wire upon the downward stroke of the plunger which carries the upper portion of the device, the ferrule being pinned upon said downward stroke and a new length of wire fed upwardly upon the return upward stroke of the press.

The invention will be more clearly understood from the following detailed description and accompanying drawings, in which- Figure 1 is a front elevational view of a ferrule pinning device made in accordance with the present invention; 2

Figure 2 is a horizontal sectional view taken along line 2-2 of Figure 1;

Figure 3 is a top plan view from the top of Figure 1;

Figure 4 is a view looking from the rear of Figure 3;

Figure 5 is a longitudinal sectional view taken along line 5--5 of Figure 1;

Figure 6 is a fragmental sectional view taken on line 6--6 of Figure 2 and showing the device just piror to the wire cutting operation;

Figure 7 is a similar view with the press plunger in lower position.

Referring now to the drawings in detail, the numeral |0 indicates the stationary bed plate of a power press or foot press having an up and down reciprocating plunger ll. Secured to the bed plate In by any suitable means as for instance clamps I2 is a base block l3 upon which the lower portion of the device is suitably supported.

Carried by the central front portion of the base block l3 is'a slideway M to which are secured front plates I5 by means of screws l6. Slidably mounted between the sides of the slideway l4 and plates I5 is a lower socket portion I'I having a V-shaped cutout l8 best shown in Figures 1, 2 and 5. The socket portion I1 is vertically adjustable by means of a screw I9 centrally located at the bottom of the slideway I l. The socket portion H is pressed against the screw l9 by means of springs 20 which bear against the top of said portion I1 and an upper socket portion which is in the form of a plate 2| secured in place by screws 22. The plate 2| has a central arcuate cut-out 23 which with the V-shaped cutout |8 forms a socket 24 for the reception of the tip or ferrule 25 to be pinned to the end of the shank 26 of an umbrella 21.

The base block is provided with a vertical opening 28 the upper portion of which is screw threaded as at 29 to receive the screw threaded end 30 of a bushing 3|. Rotatably mounted on said bushing 3| is a disk 32 having ratchet teeth 33 and provided with radially spaced apart holes 34 equal in number to the number of teeth 33. The lower portion 35 of the disk 32 bears against the top surfaces of plate 2| and together with a hardened bushing 36 in the base block l3 forms wire cutting means. The said portion may if desirable be in the form of a separate hardened disk secured to the disk 32 or the two disks may be integral as shown. Where the disks are separate, the lower disk 35 will be provided with holes in continuation of the holes 34.

of the device looking Passing through the bushing 3| is a rod 37 which at its upper end has a screw threaded portion 38 which enters a screw threaded opening 39 in a shaft 40 having a lower screw threaded reduced portion 4| screw threadedly secured to a carrier head or block 42. The rod 31 is locked in place against the reduced shaft portion 4| by means of a nut 43. The upper part Of the shaft 49 is engagedlysecured to, or carried by the press plunger The block is provided near the rear thereof with a pair of spaced apart guide rods 44 which have sliding engagement in holes 45 in the base block I3. Suitable lubricating cups 46 are provided for lubricating the said rods as they travel up and down inv the. holes'45. The

carrier head or block 42 has a roller 4'! rotatably secured thereto by means of a stud 48, the said roller being in engagement with a cam surface 49 at the top of a plate 50 secured to a brake arm by means of a screw 52. The brake arm 5| is rotatably mounted on the bushing 3| beneath a head 53 on said bushingand is provided with an opening 54 in which there is slidably mounted a pawl 55 having a hole 55 inwhich is located a compressionspring 51 which is held in place by means of a plate 58 secured to the brake arm 5| by one or more screws.59, The spring 56 normally maintains the pawl 55 in contact with one of the teeth 33. The brake arm 5| is under control of a spring 50 anchored at one end to a stud 6| on said arm and at the opposite end on a hook 552 secured to the baseblock |3 by screws 63. (See Fig. 4.) A second pawl 64 engages one of the teeth 33, said second pawl being spaced 90 from the pawl 55 and slidably mounted in a block 65 secured to the base block |3 by screws 65. The said pawl 54 is provided with a hole 6'! in which there is located a coiled tension spring 68 which exerts a pressure against the said pawl and a maintain the pawl in engagement with the toothed disks 32. The plate is secured to the block 65 by screws and 1|.-

The bottom'of the rod 31 has a reduced portion 72 which in turn has a reduced threaded end 73 for the reception of a cylinder 14 which forms a part of a wire feeding mechanism, a description of which follows.

Pins 75 for pinning ferrule to stem 25 at 75 (see Fig. 5) are cut from a wire 7'! supplied to the device from a source not shown in the drawings. The wire feeding mechanism includes a guide plate 18 secured to the underside of the base block 13 by screws 79. The saidguide plate is provided with an openin 80 through which the wire passes upwardly and is normally frictionally held against by a fiat spring 8| secured to the said plate 18 by a screw 82. The base block I 3 is provided with a slideway 83 at the left side thereof as Viewed in Figs. 6 and '7 in which is slidably mounted a wire feed bracket 84 which is provided at one end with a hole 85 which embraces the reduced rod portion 12. Intermediate the end thereof the bracket 84 is perforated as at 85-85 for the passage of the wire 77 therethrough. A plate '85 movably supported at one into position to contact the cam surface 53 for actuating the device for cutting the wire to form a pin 75.

The operation of the device is as follows:

Initially, wire 71 is threaded upwardly through the opening 80, and bushing 35 into an opening 34 to approximately the top of the toothed disk 33. The press is then actuated to move its plunger I downwardly, thus carrying with it the shaft 43, rod 3'1, head 42 and roller 41. The first part of this downward movement is an idle movement on the shoulder formed at the juncture of the rod 31 and its reduced portion 12 moves towards the top surface 9| of the bracket while the cylinder '14 moves away from the bottom surface 92 of said bracket. During the next part of the movement, the roller 48 strikes against the cam face 44 and moves the brake arm and its pawl 55 to the dot and dash position shown in Figure 2, thus rotating the toothed disk 32 the distance of one tooth against the tension of the spring 65 and spring pressed pawl 64. During the said rotation, the pin 15 has been cut from the wire 17 by the shearing action between the bushing 38 and the disk portion 35, the said pin being carried the angular distance between two teeth 33 or holes 34. During the part of the downward movement just described and upon further downward movement of the moving parts above enumerated, the shoulder 59 contacts the bracket surface 9| and moves said bracket down, the wire 11 meanwhile being held against downward movement by the spring 8| thus permitting the loosening of the tension between the said Upon the upward stroke of the press plunger, a shoulder 74a formed by top of the cylinder 14 contacts the bottom surface 92 of the bracket 84 and carries same upwardly. This upward movement of the bracket 84 causes the spring 8| to release the wire Ti and the plate 86 to press against said wire and feed same upwardly into the disk 32 a sufficient distance for another pin length. The above operation is repeated until the disk 32 has been moved through an arc of 90 after which the umbrella or cane to be operated upon is inserted into the socket 24. With the umbrella or cane in position and upon the next downward stroke of the press a pin-like tool 93 carried in a chuck 94 on head 42 will push the pin 75 into of pin out off may be adjusted by unscrewing or tightening the cylinder M on the threaded end 73 vice for pinning ferrules to the ends of umbrellas and for canes of various diameters.
